4. Two current-carrying loops are arranged so that they form concentric circles as shown in the figure below. The bigger loop (radius = 0.80 m) has a 5.00 A-current passing through it. The smaller loop has a radius of 0.40 m. Draw the magnetic field (use 2 different colors) produced by each current carrying loop. Determine the magnitude of the current in the inner loop so that the resulting net magnetic field at the center of the concentric loops will be zero. (Hint: This will only happen when the directions of the magnetic field produced by each loop are opposite in direction)
